Question

I need help is it A B C or D

Answer 1

I would say c as the answer

Answer 2

Data is Linear.
Find slope using first and last data points (1,5) and (13,20)
$m = \frac{20-5}{13-1} = \frac{15}{12} = \frac{5}{4}$
Then us point-slope form using point (1,5)
$y - 5 = \frac{5}{4}(x-1)$
Therefore answer is option D
